TYPOGRAPI-IICAL LINE GOMPOSING AND CASTING MACHINE.

Application filed May 26. 1925, Serial No.

This invention relates to typographical line composing and casting machines, such kas those known commercially under the trade mark Linotype and kindred machines which produce cast lines of type or slugs. More particularly it relates to those machines-wherein, during the casting operation, the composed line of matrices is supported in a vise frame between two vise jaws of which the left-hand one is operatively engaged with a wedge block located outside of the vise cap and there'engaging with a movable wedge which servesl to move the said left-hand vise jaw towards the right-hand one for effecting what is known as the second justification.

In `a machine of this particular construction there has heretofore been provided a serratedjbar or rack engaged by the lefthand vise jaw and projecting to a very considerable extent beyond the left-hand end of the vise cap. This bar or rack'has consequently been very liable to ydamage by operators passing to and fro atv that side of the machine. y

The object of the present invention is so to constructl the vise mechanism as to overcome the aforesaid difiiculty, this being attained by locating the rack within the head of the vise itself and thereby avoiding the necessity for having any vital or delicate parts overhanging the left-hand end of the vise cap. f

The invention will now be described by reference to the accompanying drawings in which Figures 1, 2 and 3 are representative of one constructional form and Figure 4 is representative kof a modification thereof, the first three figures being respectively a front elevation, 'a left-hand side elevation, and a plan, while Figure 4 is also a front elevation.

In the constructional form vshown in Fig-- ures 1, 2 and 3, the rack 1 is at one end slid ably secured, as by a slot-and-screw connecl tion 2, to the head 3 of the vise frame 4, and

at the other end it is attached, by screws 5, to the wedge block 6. With this wedge block, the vertically movable wedge 7 cooperates in the well-'known manner to move the lefthand vise jaw 8 rightward for effecting the second justification.

The vise jaw 8 is normallyengaged with the rack 1 through a detent 9 which is vertically slildable in a recess in the so-called 32,890, and in Great Britain June 12, 1924.

vise-j aw casting 10, which recess also houses a spring 11 which always tends to hold the detent 9 in engagement with the rack 1. The detent 9 -is pivoted to the horizontal arm of a bell-crank lever 12 which, by a screw' or pin 13, is pivoted to the vise-jaw casting 10 and whose upstanding arm, through a screw-threaded extension 14, pivotally or loosely engages with an enlarged hole or slot in the known releasing rod 15, as shown in Fig. 3. l

The lever extension 14 penetrates a narrow slot 16 (shown in dotted lines in Figure 3) formed in the cap or top of the vise head 3, this slot being of such length as will allow the vise-jaw 8 itsyfull range of motion.

The releasing rod 15, as ordinarily, is longitudinally slidable in 'a groove 3aL in the top of the viseV head 3, and provided at its righthand lend with an upstanding thumb-piece 17 by which it can be moved rightward in opposition to the spring 11, for effecting the disengagement of the detent 9 from the rack 1, prior to the adjustment in the wellknown manner, by means of the upstanding plate 18,v of the vise-jaw 8, this plate, as ordinarily, being attached bymits sliding rod 19 and a vertical in 20 to the vise-jaw casting 10. The sliding rod 19 underlies the releasing rod 15, and both of said rods are retained in sliding connection with the vise head, by a plate 21 screwed to the latter.

When, with the foregoing arrangement, it is desired to adjust the vise-jaw 8 to a new position, the operator grasps the two members 17, 18, so as to move the former towards the latter and thereby disengage the detent 9 from the rack land then moves these members to bring the vise-jaw to the desired position, which latter can be -decided by reference to a scale 22, Figure 3, the subsequent release of the members 17, 18, perf mitting t-he detent to again engage with the rack under the influence of the spring 11, and therebylock the jaw in the position thus v arrived at. i

As it is sometimes required'to bring the left-hand vise-jaw 8 into contact with the right-hand vise-jaw 23, as when blank slugs are to be cast, and the jaw 8 must be reset in its original position after each such operation, the foregoing construction calls for the accurate determination of such position Y by meansoi the scale 22 which may involve some slight delay. rlhis delay, however, can be entirely avoided my adopting the construction shown .in Figure t, in which the detent 9 and' .lever l2 are mounted inablock 24 formed indepei-idently ol' the' vise-jaw casting 10, and the rod 19 is att-ached to this bloeit, instead ol", as inthe betere described example, to the casting l() itself. ln this arrangement therefore, the vise-jaw S which abuts block Qfjl can be. moved into position for casting blank slugs without disturbing the setting of the block 23a, and after such casting the said jaw can be moved outward ly into Contact with'- the block which accurately determines its position without reference to any scale.

It preferred to provide a stop 25 which can be z i'djusted to, and cl'amed in, any desired position along the groove 3', and this serves to pil-event any unintentional outward detiection oi the block 24v, when the Vjaw 8 contacts with it. o

Having described my invention, I declare that what I claim and desire to secure by lletter's Patent' iszl'. ln a typographical line composing and slug casting machine, the combination of a vise trame, a vise jaw supported in the head ot' that iframe, a guide in sai-d' head where-in the aw isv movable, a locking detent for the said jaw located' within said head, a rack bar the toothed portion ot'which is engaged by the detent and located Vwholly within the head, and a wedge block i'ast to the rack bar and located externally oit' the vise head'.
